Any Logic behind thinkpad model numbers?

I was wondering if anyone knows the logic behind the model numbers of thinkpads ... I can't see any sort of a pattern between different lines of machines, and sometimes I wish they had a simple scheme so that I can look at the machine description and have a rough idea of what it has, or atleast if it is high-end or entry level. Obviosuly after looking at thinkpads for a while I know where to look for description and after a period of time I do know what series has what, but I wish it was simpler.

Anyone knows if there is some logic behind these model numbers that I am failing to see?

T = Thin
R = Rugged
X = Xtra small
A = All-in-one
G = Good
Z = Z latest style

I'll second that except:

T= Used to be thin prior to T61.

Are you literally asking about the numbers? For The modern series, it's obvious: the numbers started at 20 and went up with new technologies. The R series started with 30 because it was started after the other series, so IBM tried to help it catch up. After Lenovo took over, they started all series at 60, thus skipping the X5* and the T5*. For the classic Thinkpads (240, 390, 570, 600, 701, whatever), it's more arbitrary and thus confusing.

My R50p is far less rugged than most of the T-series models I've owned.

I think "G" stands for "gross". It's such an ugly series.

Now it stands for "Thick".

See an old thread on the same topic.

Or maybe Sri's asking about the MODEL TYPE numbers. I can't for life of me figure out why a T61 has ten MT numbers (6480 and 6481 and 7658 through 7665). I'd guess it's because of the major subsystems that can be configured, but why such a disparity between the numbers?

Hello

I would say this:

T = Thin Thing TempTing for Thinking
R = Reliable foR that money
X = eXtra small and eXtra light and eXtra seXy
A = All-in-one bunch
G = Great for table
Z = have some extraZ

This was the info I was asking about, not the T R X classification!

do not look for logic where it is not necessary to be used.
SN, model type, PN etc. are just a bunch of combinations in some systems.
anyway even if you found it, it would not make any difference in using TPs or you try to prove that IBM/Lenovo is totally ingenious?

I am just curious, that is all.

Has Lenovo hinted at what the next lettered model lines will be?

How about H?

I see.

In my opinion there's no logic behind those model and type numbers and they're just there for identification purposes.

Probably Hot.

The model numbers are a carry over from an uber-model numbering approach that IBM used right across many of its product lines. There was definitely some overall plan in that approach, though what that was is probably related to manufacturing and support systems etc and is not inituitively obvious.

Lenovo has continued the general 4 digit model scheme but seems to have jumped the primary numbers for new ThinkPad model numbers up into an entirely different set than IBM had previously used for ThinkPads and may therefore have a different underlying rationale for the way numbers are assigned within the scheme.

Cheers,

In general, starting with the recent Lenovo produced machines? The 1xxx models are the value line, while the 2xxx are the heavy hitters. In general, within the line, the higher the numbers, the better the machine and its accompanying warranty.
